[llvm-commits] [PATCH] TargetData::getIntPtrType() to return IntegerType

[Jay Foad]

The attached patch lets me avoid some casts to IntegerType in some
code I'm working on. Thoughts? It passes regression tests and cfe and
llvm-gcc still build.

It's a bit unfortunate that TargetData.h has to include
DerivedTypes.h, but otherwise this would break code like:

  const Type *Ty = TD->getIntPtrType();

which now needs to know that IntegerType is derived from Type.

Thanks,
Jay.
